Publish message bigger than max UDP datagram size

[mauropasse]

Hi, I'm doing some tests publishing messages of different sizes. When the message size is bigger than the maximum UPD datagram size, an error arises:

250002345 ERROR src/multicast/network.c@416: MulticastSendComplete status=EMSGSIZE

which means that the datagram couldn't be sent because it was too long.

Is there any implemented workaround for this, like splitting the message into chunks?

DPS itself doesn't do segmentation and reassembly. This could be done at the rmw_dps layer and potentially pushed down into DPS.
